Agreed. I ended up making a patch for base-config trying to
generating the needed locale, and unsetting LANG and LANGUAGE if is
isn't available. Both LANG and LANGUAGE is needed, to make it
possible to use a prioritized list of languages. It is using LANG to
determine what to put in /etc/locale.gen.
Here is the patch. Should I register it as a bug against base-config?
I tested it and using it made dselect show translated text. (tasksel
did not find any tasks and aptitide wasn't installed. :-)
There is a problem when running base-config using 'script'. I didn't
understand what the problem was, but the 'Configuring the base
system...'-part of base-config never started. It did run validlocale,
but did not seem to run locale-gen. I worked around this problem by
setting BASE_CONFIG_IN_SCRIPT=1 manually.
Anyway, here is the patch, relative to the current anonymous CVS HEAD
version. The two last files (validlocale and validlocale.8) are new.
